Description

Technical Field

[0001] This utility model belongs to the field of laser cutting equipment and relates to a dust extraction device for laser cutting. Background Technology

[0002] In the field of glass processing and manufacturing, laser film removal technology has become a key method for removing film layers from glass surfaces due to its significant advantages such as high efficiency, precision, and non-contact operation. This technology utilizes the interaction between a high-energy laser beam and the film layer on the glass surface, causing the film layer to rapidly heat up, vaporize, or decompose, thereby achieving a fast and thorough film removal effect.

[0003] In actual production, the glass surface is usually cleaned before laser coating removal to allow dust and other particles to fall off the outer edge of the glass, ensuring the quality of the coating removal. However, if the particles on the outer edge of the glass are not dealt with in time, they will escape. Some of these escaped particles will re-adhere to the glass surface, causing secondary contamination to the cleaned or removed glass, seriously affecting the cleanliness of the glass and the quality of the product. Utility Model Content

[0004] The purpose of this invention is to provide a dust extraction device for laser cutting, which solves the problem of particulate matter escaping from the glass periphery by increasing the extraction range.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A dust extraction device for laser cutting, comprising:

[0007] A carrier plate is set on a workbench and is used to support a fixture for placing the product to be cut. The carrier plate is provided with a second opening.

[0008] A fixture is mounted on a carrier plate to fix the product to be cut. The fixture has a third opening and a notch communicating with the third opening so that the dust generated during laser cutting can be drawn away through the notch and the third opening.

[0009] A dust extraction hood is installed at the bottom of the workbench, and the workbench above it has a first opening. The first opening, the second opening, and the third opening correspond to each other to form a dust extraction channel. The lower end of the dust extraction hood is connected to a dust filter on the outside of the workbench through a pipe for filtering the extracted dust.

[0010] The omnidirectional ball is set on the workbench, and the carrier plate is suspended in the air by the omnidirectional ball, so that the bottom of the carrier plate is connected to the dust extraction channel.

[0011] As a further improvement of one embodiment of the present invention, a roller assembly and a cylinder assembly are respectively provided on opposite sides of the worktable. The cylinder assembly pushes the carrier plate so that the side of the carrier plate abuts against the roller assembly, thereby fixing the position of the carrier plate on the worktable.

[0012] As a further improvement of one embodiment of the present invention, the cylinder assembly includes a cylinder bracket fixed on the workbench, a cylinder is provided on the cylinder bracket, a push plate is provided at the piston end of the cylinder, and the push plate pushes the carrier plate under the drive of the cylinder so that its other side abuts against the roller assembly.

[0013] As a further improvement of one embodiment of the present invention, the roller assembly includes a plurality of rollers arranged in sequence, the rollers being mounted on the worktable via short shafts; the distribution of the rollers corresponds to the contour of the carrier plate.

[0014] As a further improvement of one embodiment of the present invention, handles are provided on both sides of the carrier plate.

[0015] As a further improvement of one embodiment of the present invention, the outlet of the dust extraction hood is located at the lowest end of the dust extraction hood, and the inner wall of the dust extraction hood is a slope facing the outlet.

[0016] As a further improvement of one embodiment of this utility model, the dust removal filter is a cabinet-type filter, which is internally divided into a lower filtration chamber and an upper exhaust chamber by a partition. The filtration chamber is provided with an inlet connected to a pipeline for receiving airflow containing dust drawn from the dust extraction hood. A filter is installed on the partition. When the airflow containing dust enters the filtration chamber, the dust is trapped by the filter, achieving gas-solid separation. The filtered clean airflow then enters the exhaust chamber upwards.

Example

[0040] See Figures 1-3 As shown, a dust extraction device for laser cutting is designed to efficiently remove dust generated during cutting, improve the working environment, and ensure equipment and product quality. The dust extraction device includes a carrier plate 2, a fixture 4, a dust extraction hood 5, a directional ball joint, and a dust filter 6. Wherein:

[0041] The carrier plate 2, serving as a support component, is stably placed on the workbench 1. The second opening on the carrier plate 2 precisely corresponds to the first opening on the workbench 1 and the third opening on the fixture 4, together forming a crucial dust extraction channel. This corresponding opening design ensures that dust can pass through smoothly, preventing accumulation at the joints of various components.

[0042] The fixture 4 is fixed to the carrier plate 2, and its function is to stabilize the product 3 to be cut. The third opening on the fixture 4 is connected to the notch 41. In this embodiment, the product 3 to be cut is curved glass, so the height of the fixture 4 varies. The notch is located on the side of the fixture 4 with the lower height, which is more conducive to collecting the dust generated during laser cutting.

[0043] The dust extraction hood 5 is installed at the bottom of the workbench 1, and its lower end is tightly connected to the dust filter 6 on the outside of the workbench 1 through a pipe. When the dust extraction device is started, the dust extraction hood 5 generates a strong suction force, sucking in the dust in the dust extraction channel and conveying it to the dust filter 6 for filtration.

[0044] The omnidirectional ball is mounted on the workbench 1, and the carrier plate 2 is suspended in the air with the help of the omnidirectional ball. This design not only reduces the friction between the carrier plate 2 and the workbench 1, making it easier for the carrier plate 2 to move flexibly to adjust its position, but also ensures that the area below the carrier plate 2 and the dust extraction channel are always unobstructed.

[0045] In this embodiment, roller assembly 7 and cylinder assembly 8 are reasonably arranged on opposite sides of the worktable 1, and the two work together to achieve precise positioning of the carrier plate 2 on the worktable 1.

[0046] Specifically, the cylinder assembly 8 includes a cylinder bracket fixed to the worktable 1, which provides stable support for the entire assembly. The cylinder is mounted on the cylinder bracket, and its piston end is equipped with a push plate. When the cylinder is activated, the piston drives the push plate to move smoothly, and the push plate contacts the carrier plate 2 and applies a thrust, causing the side of the carrier plate 2 to accurately abut against the roller assembly 7. In practical applications, the cylinder can also be replaced by an equivalent component with similar linear drive function, such as an electric push rod.

[0047] The roller assembly 7 consists of several rollers arranged in sequence, each reliably mounted on the worktable 1 via a short shaft. The rollers are carefully positioned to precisely correspond to the contour of the carrier plate 2, ensuring uniform force and positional stability after the carrier plate 2 comes into contact with it. Rollers with bearings can also be selected to reduce rotational friction.

[0048] To facilitate the movement of the carrier plate 2 by the operator, handles 21 are provided on both sides of the carrier plate 2. The shape and size of the handles 21 can be optimized according to ergonomics to make them easy to grip, further improving the practicality and ease of operation of the device.

[0049] In this embodiment, the outlet of the dust extraction hood 5 is located at the bottom of the dust extraction hood 5, and the inner wall of the dust extraction hood 5 is a slope facing the outlet. This structural design allows the dust generated during laser cutting to be drawn more smoothly along the slope of the inner wall of the dust extraction hood to the bottom outlet under the suction force of the dust extraction device, and then enter the subsequent dust filter for treatment. Compared with the traditional dust extraction hood structure, this greatly reduces the residue and accumulation of dust inside the dust extraction hood, improves the dust extraction efficiency of the dust extraction device, ensures the cleanliness of the laser cutting environment, and thus improves the quality and stability of laser cutting.

[0050] In this embodiment, the dust filter 6 is a cabinet-type filter, internally divided into a lower filtration chamber and an upper exhaust chamber by a partition. The filtration chamber has an inlet connected to a pipeline to receive dust-laden airflow drawn from the dust extraction hood 5. The filter mounted on the partition is a key component for gas-solid separation. When airflow enters the filtration chamber, the dust is effectively trapped by the filter, achieving gas-solid separation, and the filtered clean airflow smoothly enters the exhaust chamber. In practical applications, different types of filters, such as cartridge filters and bag filters, can be selected to meet the filtration needs of different dust characteristics.

[0051] The dust extraction device (exhaust fan) installed inside the exhaust chamber is the power source of the entire dust extraction system. It can generate a strong and stable suction force, ensuring that the airflow continuously enters the filter chamber from the dust extraction hood 5 through the pipeline for filtration. The exhaust fan can also be replaced by a centrifugal fan or other equipment with similar exhaust functions.

[0052] In addition, the dust filter 6 is equipped with a first switch door 61 and a second switch door 62. The first switch door 61 facilitates the regular replacement of the filter by the staff to ensure the filtration effect; the second switch door 62 is used to clean the dust trapped in the filter chamber, maintain the normal operation of the equipment, and extend its service life.

[0053] The dust extraction device provided by this utility model is an integral part of a complete laser cutting equipment system, sharing the power supply system, air supply system, and control system with the laser cutting equipment. Through linkage with the laser cutting equipment, the dust extraction device can be automatically controlled to start and stop according to the laser cutting progress, achieving efficient and precise dust extraction operation and reducing the impact of dust on the cutting equipment and products.

[0054] This invention efficiently draws the dust generated during cutting from the notch 41 on the fixture 4, below the carrier plate 2, and the dust extraction channel into the dust extraction hood 5 and then transports it to the dust filter 6 for filtration. By increasing the extraction range of the dust extraction channel, it solves the problem of the escape of particles from the glass periphery, thereby improving the quality of the laser cutting environment and reducing the impact of dust on the cutting equipment and products.
